Abstract:
A light extraction film having nanoparticles with engineered periodic structures. The light extraction film includes a substantially transparent substrate, low index one-dimensional or two-dimensional periodic structures on the substrate, and a high index planarizing backfill layer applied over the periodic structures. Light scattering nanoparticles are either applied in a layer over the periodic structures or included in the backfill layer.
Abstract:
The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modifation of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.
Abstract:
An electronically switchable privacy films suitable for use in display devices are described. The electronically switchable privacy film comprises a pair of mutually opposing transparent electrodes; an optically transparent microstructured layer disposed between the transparent electrodes, the microstructured layer comprising a plurality of microstructured ribs extending across a surface thereof such that the microstructured ribs form an alternating series of ribs and channels; and electronically switchable material disposed in the channels, the electronically switchable material being capable of modulation between high and low absorption states upon application of an electric field across the transparent electrodes.
Abstract:
An article including an airfoil or hydrofoil is disclosed. On at least a portion of a surface of the airfoil or hydrofoil there is a seamless film having a series of substantially parallel peaks separated from each other by a series of substantially parallel valleys on a patterned first surface of the film, wherein the seamless film has a long dimension that is at least two meters long substantially aligned with the span of the airfoil or hydrofoil, and wherein an angle between the parallel peaks and valleys to the long dimension of the seamless film is at least five degrees. Methods of making the article are also disclosed.
